تهدف هذه الدراسة إلى تحديد نزر بعض العناصر المعدنية الثقيلة pb, Cd, Cu, Zn & Fe في أوراق و ساق نبات القصب. جمعت العينات من عشرين موقعاً، و قسمت في أربع مجموعات بحسب الحركة المرورية و الأنشطة البشرية، و قد تم تحديد تراكيز العناصر باستخدام مطيافية الامتصاص الذري. أظهرت النتائج ارتفاع تراكيز كل من الرصاص، الكادميوم و النحاس في أوراق و ساق القصب مما سمح باستخدام هذا النبات كمؤشر حيوي للتلوث بهذه العناصر المعدنية الثقيلة، حيث تراوح تركيز الكادميوم في الأوراق و الساق بين (0.231- 6.278ppm) ،و تركيز الرصاص بين 1.057-47.592ppm)) و النحاس بين (1.022-45.771ppm)، في حين بقي تركيز كل من الزنك و الحديد ضمن الحدود الطبيعية المسموح بها.
The aim of this study was to determine the trace of some heavy metals elements pb, Cd, Cu, Zn & Fe in the leaves and periderm of the Avundodonax L. using Atomic absorption spectroscopy. The samples were collected from twenty locations and divided into four groups according to traffic and human activities. The results showed an excess in the concentration of lead, cadmium and copper in the leaves and periderm of the Avundodonax L., which enables the use of this plant as a vital indicator for the pollution by these heavy metals. The concentration of cadmium in the leaves and periderm ranged between (0.231- 6.278ppm) and for lead between(1.057- 47.592ppm) and copper between(1.022 -45.771ppm). While the concentration of both zinc and iron remained within the permissible natural limits.

This study deals with the determination of the quantity of solid dust particles deposed
on the leafs of some trees along Syrian coast and the concentration of some heavy metals
in it (Zn, Fe, Pb, Cu, Ni, Cd, Co, Mn) .Some sites near to human and in
dustrials activities ,
and others near to agriculture activities , and others relatively far from pollution sources
has been selected. The results showed that the quantity of solid dust particles on leafs
trees and concentration of heavy metals in it such as (Pb, Ni, Cd, Co) increasing near the
industrials activities and dense traffic, and decreasing in the sites that relatively far from of
pollution sources. However Cypress trees attach solid quantities more than Pride of china,
following Rever red gum and Blue-leafed wattle and Oleander, and the Palm tree come in
the last.

The aim of this study isto determinat the concentration of (Pb, Cu, Cd, Co, Cr , NiZn,
Fe) in storm water and their content of sediments during four seasons, the samples were
collected in four areas along Tartous beach. After make necessary treatme
nt concentrations
of elements determination by flame atomic absorption spectrometry.The results showed a
high levels of elements iron and zinc, in stormwater (138.6 μg/l - 99.7 μg/l) and sediments
(17.863 μg/l – 138.735 ppm), in all samples and there were concentrations another
elements difference between stations and rainfalls related to the human activities.
The study focused in this research to determine the trace of some heavy metal
elements (Copper Cu, Cadmium Cd, Lead Pb) in some types of marine macroalgae
scattered on the shore of the city of Banias during 2014, using atomic absorption
spectrosco
py (technology flame Flame- AAS).
The results indicate that the concentrationsofeach of Copper, Cadmium and Lead
have a link with macroalgae types, sampling sites from direction, and Source of pollution
on the other hand; it was observed that the accumulation of heavy metals in both of
Sargassum vulgare (browen algae) and Enteromorpha linza (green algae) was more than
red algae.
Copper concentration ranged between 1.291 ppm and 11.716 ppm in the studied
species, Reaching the highest value in the Enteromorpha linzaalgae and the lowest in
Sargassum vulgarealgae, the highest value of Lead element was (59.354 ppm) in
Enteromorpha linzaand the lowest value of it was (6.46 ppm) in Ulva fasciata, While the
highest values of the element Cadmium recorded (10.457 ppm) in Enteromorpha linza and
the lowest (0.666 ppm) in Ulva fasciata.
This study deals with identifying some heavy metals (Pb,Zn,Ni) concentration in the recycledsewage in Latakia Countryside which is resulting from three treatment plants distributed over (Hebbeit, Al-Harah, MarjMoairban),2011.This research uses the El
ectro Thermal Atomization-Atomic Absorption Spectrometry (ETA-AAS) technique in determining of heavy metal elements mentioned above. This research shows a higher concentration of Zn-element (2.798 mg/L) in all treatment plants and in all seasons compared with the concentration of other elements, while Ni and Pb have recorded low concentrations (0.351, 0.243) mg/ℓ, respectively. The statistical study has demonstrated that there is a correlation varying from positive high to positive low, and sometimes to negative highs and lows, this gives clear indications for resources of pollution.
This research focuses on determining elemental concentrations of copper and lead
(Cu &pb) in the muscles and liver Boops boops kind of the estuary of the AL Kabeer
Alshemaly River and the fishing port and the promenade using atomic absorption
tech
nique.
The results showed a significant increase in the concentrations of lead during
summer 2014 in each of the muscle tissue and the liver of the fish examined (28.28ppm&
4.48ppm, respectively) at the mouth of the estuary of the AL Kabeer Alshemaly River and
the fishing port and the promenade (11.19ppm& 3.75ppm, respectively), and this could be
due to the different nature of human activities and sources of pollution to this element
between the two regions.
The results showed a marked seasonal change in the concentration of copper within
the liver tissue of fish studied, where the highest concentration in the fishing port and the
promenade( 5630.02 ppm) in autumn 2014, the Supreme( 3402.27ppm) value in the AL
Kabeer Alshemaly River the estuary of summer. While the results did not show the
variable in concentrations of copper in muscle . Theconcentrations were comparable
between the two stations somewhat, with the highest concentrations in the summer in
Bouth the fishing port and the promenade 1497.70ppm) and(1107.91 ppm) the AL Kabeer
Alshemaly River.
Results indicate that the accumulation of the studied elements (Cu &pb) in the liver
compared to muscle (and the reason is boiled physiological differences in the functions of
each of the two members) and to the existence of a good correlation between the
concentration in the muscle changes with the typical length of which points to increased
accumulation of these elements in these fish with increased growth,Noting the high
concentration of the studied elements in females more than those recorded in males.
